Glycolysis takes place in the cytoplasm of a cell as the first step in cellular respiration of the Kreb's cycle. When glycolysis occurs, it breaks down glucose into pyruvic acids in the cytoplasm.
Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes.
